The Fatal1ty B450 Gaming-ITX/ac shows us the goods with the heat sinks removed!
The VRM is in a 6+2 phase controlled by an Intersil ISL95712, it's in 3+2 phase mode and features two integrated drivers for the main 3 phase rail and one on the 2 phase rail. The SoC phases use two dual N-channel MOSFETs, and the VCore phases use one per phase. The Sinopower SM7341EHKP MOSFETs and high-power inductors should be solid for powering the new CPUs.
The memory VRM is a fully integrated controller from MPS; the MPQ8636 rated up to 20A in this case.
